Benefits of technology

[0015]It is an object of the present disclosure to provide a method for controlling interrupts in an inverter, by which interrupts are abstracted by their functionality in embedded software in an inverter to implement software irrespectively of MCUs, thereby increasing reusability of the software to shorten the development time and improving the code quality.
[0016]It is another object of the present disclosure to provide a method for controlling interrupts in an inverter, by which the software execution efficiency is increased by determining whether to perform an interrupt function according to whether the function is used or not.
[0023]According to an exemplary embodiment of the present disclosure, interrupts typically defined by MCUs are converted into interrupt IDs sorted by functionality, such that software can be implemented irrespectively of the MCUs. As a result, the time taken to develop software can be shortened.
[0024]Further, according to an exemplary embodiment of the present disclosure, when various functionalities are executed in one function for interrupts of the same MCU, the quality of software can be improved by separating functions by functionality.
[0025]Further, according to an exemplary embodiment of the present disclosure, it is possible to improve the execution efficiency of software by determining whether to execute the interrupt function dependent on whether to use (enable) it.

Problems solved by technology

Currently, such an embedded market is getting bigger with issues related to internet of things (IoT) and smart factories.
Unfortunately, the types and names of such interrupts differ from the manufacturer's cores or MCU series.
Therefore, it is necessary to change the interrupt software depending on the MCU, and it is difficult to communicate between developers using different MCUs.
Therefore, there are problems that the it is difficult to reuse the programs, and different interrupts are required for different inverters.
In addition, as shown in FIGS. 1A and 1B, the name and structure of the interrupt functions having the same functionality differ from inverters, and thus it is difficult to know what function is performed only with the interrupt function.
As a result, there is a problem that it is difficult to analyze the software.
In addition, when a single interrupt function performs several functionalities, the code complexity increases to thereby deteriorate the quality of the software.
In addition, when a functionality is added or deleted, the code reference diagram becomes complicated.
As a result, this leads to deterioration of the inverter quality, and the development time of the inverter software becomes longer.

Embodiment Construction

[0030]Exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings to facilitate understanding of the configuration and effects thereof. The scope of the present disclosure may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the inventive subject matter to those skilled in the art. In the drawings, the size of some of the elements may be exaggerated for convenience of illustration and not drawn on scale for illustrative purposes.

[0031]It will be understood that when an element such as a layer, region, substrate, or panel is referred to as being “on” or “connected to” another element, it can be directly on the other element or intervening elements may also be present. In contrast, when an element is referred to as being “directly ...

Abstract

Disclosed herein is a method for controlling interrupts in an inverter. If a control unit checks that an interrupt is issued in main software while an inverter is operating, the control unit analyzes the type of the interrupt. The interrupt is converted into an interrupt ID sorted by functionality. If the interrupt ID is a previously registered interrupt ID, an interrupt function corresponding to the registered interrupt ID is executed.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the priority of Korean Patent Application No. 10-2016-0150879 filed on Nov. 14, 2016, in the Korean Intellectual Property Office, the disclosure of which is hereby incorporated by reference in its entirety.BACKGROUND1. Technical Field[0002]The present disclosure relates to a method for controlling interrupts in an inverter.2. Description of the Related Art[0003]Typically, an inverter receives AC mains electricity to converter it into a DC power, and then converts it again into an AC power suitable for electric motors to supply it. Such an inverter effectively controls an electric motor, thereby reducing the power consumption of the motor to improve energy efficiency. Since more than 50% of the world's electricity is currently consumed by electric motors, it is necessary to reduce electricity consumption by increasing energy efficiency with such inverters. Electric motors have different capacities depending on their...
